Introduced Species Effect on Ecosystems

In the 1940's Argentina wanted to start fur trading. In order to do this they released 50 North American Beavers into the wild. The results have been disastrous. Here is a link to an article covering this.

Keep in mind that an ecosystem is a lot like a row of dominoes. If one thing changes, then all things will change. Just like the dominoes, when one falls the rest follow.

Ecosystem PBL

As all of you should know by now, we are currently doing a project on an animal. We are taking that animal and learning everything about it. We are also learning everything that we can about its ecosystem. Below I am going to give you some examples, definitions, and links. Remember you have a glossary in the back of your science journal.
 Inherited Trait- Something that an organism is born with. Color of petals, hair color, eye color, etc.

Adaptations- changes that are made to an organism over time that help the organism survive in its habitat. It is an inherited Trait.
Examples: Whale and Dolphin blubber, 

Learned Behavior- Something that you do that you are taught or have learned through experience. Examples: Dog fetching or sitting on command, speaking a language, reading, etc.

Instinct- Behaviors that animals are born knowing how to do. Examples: Spider building a web, bird building a bird nest, sea turtles going into the ocean after hatching on a beach.
